出器の磁気コア構造。 Magnetism of a current detector comprising an E-shaped magnetic core and an I-shaped magnetic core, and an EI-shaped magnetic core formed with a magnetoelectric conversion element interposed on the top surface of a protrusion located at the center of the E-shaped magnetic core. In the core structure, the I-shaped magnetic core is formed by a first magnetic core part, a second magnetic core part, and a third magnetic core part divided into three parts in the length direction, and each part is joined to form an EI-shaped magnetic core at the time of mounting. A magnetic core structure of a current detector characterized in that mutual bonding surfaces are mirror-finished in advance so that they can come into close contact with each other during bonding.
